Assuming Responsibility

In an increasingly complex world, in which ecological and social concerns have become just as relevant as the challenge of economics, adopting a sustainable approach to business activities is essential to achieve long-term success.

Sto embraces its responsibility to contribute to the fulfilment of the 17 Sustainable Development Goals (SDGs) of the United Nations and to react to the key trends.

Our vision is to become a technology leader in the humane and sustainable design of built living spaces, worldwide.

Sto's core business is the manufacture of facade systems that contribute to significant savings in energy use through the effective insulation of buildings. Sto's energy efficient façade systems make a significant contribution to climate and environment protection and also improve the living comfort and quality of buildings.

ISO Certification

The Sto Group has established a comprehensive quality and environmental management system in the production area, whereby all production locations are recorded and audited internally. 21 of the 27 production sites in total are additionally certified externally in accordance with international standards such as ISO 9001, ISO 14001, or SHARP in order to document the high level of quality.


Commitment to social issues forms part of a long-standing tradition at Sto. We assume responsibility towards our employees as well as the places we work in and the people we work with. Sto participates in the United Nations Global Compact, a worldwide pact between more than 8,000 companies and the UN.

Sto Foundation

Alongside fundraising projects selected by the company, the non-profit Sto Foundation is the cornerstone of our charitable activities. Social responsibility for Sto does not end at the factory gates and Sto supports many of our employees as they commit themselves to social projects outside of work.
